What happens to voltage in a parallel circuit when more branches are added?

In a parallel circuit, the voltage across each branch remains constant regardless of the number of branches added. Each branch is connected directly to the voltage source, so they all experience the same voltage. This is a fundamental characteristic of parallel circuits and is essential for understanding how they operate.

When additional branches are added to a parallel circuit, they provide alternate paths for current to flow. While the overall current in the circuit may increase due to the additional paths, the voltage across each individual branch stays the same as the source voltage. This understanding is critical for electrical circuit analysis and design, particularly when calculating current distribution and ensuring all components receive the appropriate voltage for their operation.
